It's exciting, isn't it? Clicking on it and wondering whether you might be able to add to it, or finding out what someone else has been up to?
Then people start responding, and before you know it there are like 30 or so responses, and you realise that you preferred it when it wasn't so popular. And that the person that started the thread didn't really have a point, and that your response to it was fairly self-centred anyway.
Still, someone posting something, eh? Isn't it?
